 5  This example shows usage of the PixelMap helper to easily treat a single strip as a horizontal or
 6  vertical grid for animation purposes.
 7  
 8  For NeoPixel FeatherWing. Update pixel_pin and pixel_num to match your wiring if using
 9  a different form of NeoPixels. Note that if you are using a number of pixels other than 32, you
10  will need to alter the PixelMap values as well for this example to work.
11  
12  This example does not work on SAMD21 (M0) boards.
